Discussion:

The circle above is plotted at the June 2012 expected diameter for Ruriko of 35 km. The estimated diameter has since been revised (as at Oct 2014) to just 14 km making the probability of a hit even smaller. With no positive chords we cannot say where the actual path was, so the circle has been plotted on the predicted path.
